Title: Multi-color image output device
Inventor: TSUKADA SHIGERU
IPC: H04N1/113
Filed: 1987-03-25
Abstract: PURPOSE:To enable the cost reduction of a product, by a method wherein a plurality of laser beams are directed onto mirror surfaces of a single resonance scanner mirror, and separate photosensitive bodies are scanned with the reflected light thereof. CONSTITUTION:Laser light sources 1a, 1b are disposed so that laser beams 3a, 3b emitted from the laser light sources 1a, 1b have the polarizing characteristics of P-wave against polarizing beam splitters 5a, 5b. The laser beams 3a, 3b go straight as they are to reach a resonance scanner mirror 8. The resonance scanner mirror 8, having reflecting mirrors on both surfaces, can reflect and scan the laser beams 3a, 3b, separately. On the other hand, laser light sources 2a, 2b are further disposed below the laser light sources 1a, 1b, and laser beams 4a, 4b from the light sources 2a, 2b are changed their path upwards by mirrors 7a, 7b to pass through 1/2-wavelength plates 6a, 6b. Because these beams show S-wave, they are reflected in the polarizing beam splitters 5a, 5b to reach the resonance scanner mirror 8 through the same light paths as the laser beams 3a, 3b.

Title: Apparatus for preventing separation of air flow in air passage of compressor used in auomotive gas turbine
Inventor: NAKANISHI KEIICHI
IPC: F04D29/00
Filed: 1979-06-12
Abstract: PURPOSE: To enhance the turbine efficiency, by providing a plurality of vortex generators on the wall surface of air passages of compressor along the air passages, and thereby preventing separation of air flow in the air passages of compressor.  
     CONSTITUTION: A plurality of vortex generators 20 are provided on the outer wall surface B of compressor where air flow tends to cause separation, circumferentially of the compressor and along the air flow with their axes being in parallel with the air flow caused when inclination angle θ of guide vanes 10 is zero. In case that the inclination angle θ of guide vanes 10 is zero, resistance of vortex generators 20 to air flow is made minimal when air flow is caused, so that any vortex is not generated. In case that guide vanes 10 are inclined, on the other hand, vortices generated arround vortex generators 20 are separated and form vortex filaments, which flow downward along the wall surface. With such an arrangement, separation of air flow can be prevented by affording energy possessed by main flow to air flow near the wall surface having a lower energy and almost causing separation.

Title: Etching device
Inventor: YAMADA SHIZUHIRO
IPC: H05K3/06
Filed: 1980-05-31
Abstract: PURPOSE: To do etching in proper quantities constantly, by controlling an injection amount from a plurality of etchant-injecting nozzles arranged along the running direction of a metal-laminated insulative board with the nozzles which are arranged along a direction opposite to the running direction and adjacently to the former nozzles.  
     CONSTITUTION: An etchant is injected through nozzles 9, 10 onto the surface of a copper-laminated board 2, for instance, being carried at a constant speed. When etching is accomplished to a sufficient extent, a copper film 4 on an insulative substrate board 3 at a part, where an etching resist layer is not formed, is dissolved away, so that an electric resistance on the surface of the board 2 increases abruptly. In consequence, the abrupt increase of the electric resistance between brushes 14 and 15 is detected by a resistance-measuring device 16. The pressure of a pressure-variable pump 17 is lowered in accordance with the detected resistance increase, so that the injection amount of the etchant from the nozzles 10 is reduced. As a result, etching can be done in proper quantities, even if the activity of the etchant changes, or  if a board 2 having a quitely different etching pattern surface area is carried in turn.
